In
Pittsfield,
Massachusetts,
Museum
Exhibits
So-Called
Four-Eyed
Fish.
Go ahead,
call them
four eyes,
they won't
mind. They
don't even
have
glasses. In
fact,
they're born
with two
pairs of
peepers.
"They" are
part of a
new school
of fish at
the aquarium
at the
Berkshire
Museum. Over
the past few
weeks,
aquarist
Scott Jervas
has been
busy making
homes for
two new
species of
fish,
including a
four-eyed
brackish
breed known
as Anableps.
The aquarium
also has
three new
Amazon River
natives
called
banded
cichlid.
Acquisition
of the fish
came about
as part of
an aquarist
exchange
program.
Jervas is a
member of an
online
network of
about 900
aquarium
scientists
who trade
surplus
species and
supplies as
well as
information
and tips for
managing
aquarium
life. The
four-eyed
fish are
like minnows
with
asymmetrical
eyes and a
unique
reproductive
system.
"They can
see clearly
both above
and below
water
simultaneously,"
said Jervas.
He believes
that the
whirligig
beetle is
the only
other
species with
such
specialized
vision. In
addition,
the
four-eyed
fish are
one-sided
livebearers,
meaning they
only mate on
one side.
Males whose
reproductive
organs are
on the right
can only
breed with
left-"handed"
females and
vice versa.
"People come
here and go
'Ooh, look —
piranhas!'
But there's
much more," Jervas said.
"Piranhas
are boring." Click

In Nasugbu,
Batangas,
Philippines,
Divers Plant
Giant Clams
Underwater.
Local
fishermen
weren’t
around to
see the
giant clams
gently
“planted”
around the
seabed but
in a few
years, they
will benefit
from the
clam garden
with a
bigger
harvest of
fish. Under
overcast
skies,
divers
plunged into
the calm
seas off the
picturesque
beach of
Barangay
Papaya here,
and gingerly
unloaded
giant clams
from their
boat, to
plant them
on the
seabed last
Wednesday.
By noon, a
total of 102
clams had
been seeded
among the
coral reefs.
“They’re
like
babies,”
Jess Lucas,
EVP of SM
Investments
Corp. (SMIC),
said as he
watched—from
another
boat—a diver
scoop and
pour
seawater on
two clams
before
taking them
10 feet
under water.
The
clam-seeding,
initiated by
SMIC and its
partner
World Wide
Fund for
Nature (WWF)-Philippines,
was designed
to
regenerate
the marine
life in this
part of the
South China
Sea that has
been
threatened
by
overfishing.
Clams serve
as nurseries
for small
fish,
invertebrates
and tiny
crustaceans.
“If you put
clams, other
[creatures]
will come.
Fish, soft
corals,
seaweeds,
snails,
lobsters,
what have
you,” said
Dr. Suzanne
Mingoa-Licuanan
of the UP
Marine
Science
Institute
who oversaw
the
clam-seeding.
“Giant clams
serve as
nurseries
for marine
organisms.
They clean
the waters,
they
beautify the
place. In
its
entirety,
it’s all
good.”

On the Great
Barrier
Reef,
Australia,
Coral
Reefs
Bursting to
Go.
Within a few
days, in the
reefs around
the Keppels,
off
Rockhampton
and in the
Capricorn
Cays of the
southern
Great
Barrier
Reef, the
annual
spawning of
coral is
expected to
take place.
After the
bleaching of
the corals
in January
and February
in 2006,
last
summer's
spawning
effort was
half-hearted.
"This year.
they're
bursting to
go," said
Central
Queensland
University
coral
ecologist
Alison
Jones. "If
people can
get to a
reef and in
the water
between the
24th
(tomorrow)
and the
28th, about
7pm-7.30pm,
they'll have
a good
chance of
seeing it
happen." In
a
synchronised
exercise,
corals
liberate
millions of
eggs on
still
nights,
after a full
moon, when
the tides
are not so
strong, the
water
temperature
is right,
and there's
less chance
of the eggs
being swept
away before
fertilisation.
As a prelude
to the
spawning,
reef life,
little fish
and shrimps
become
wildly
agitated.
Then, small
pink balls
can be seen
bulging from
the polyp
mouths of
the corals.
"They glow
pink," Jones
explained.
"Everything
around the
reef gets
very excited
and you know
it will
happen
within half
an hour."
For 15
minutes,
millions of
the pink
globes
stream to
the surface.

In Uganda,
East Africa,
Lake
Victoria is
Now a
Protected
Nature
Preserve.
Uganda has
declared its
first ever
water
reserve,
aimed at
protecting
the
disappearing
Nile Perch
and other
species in
Lake
Victoria.
Agriculture
minister
Hilary Onek
said the
protected
area would
be called
‘Commonwealth
Lake
Reserve’, in
commemoration
of the 2007
Commonwealth
Heads of
Government
Meeting,
which ended
on Sunday.
He said the
protection
of the new
marine park
would begin
in December
and be
spearheaded
by the
agriculture
ministry
until
funding from
donors is
found. The
reserve,
stretching
6.5km south
of Munyonyo
and 10.4km
east of
Entebbe,
occupies
about 100
square
kilometres
out of the
Lake
Victoria’s
34,800
square
kilometres.
It covers
the islands
of Mukusa,
Sanga,
Kawaga Light
House, Tavu,
Kizima, Miru,
Mukusa and
part of
Kimmi, which
are all
uninhabited.
Commercial
fishing will
not be
allowed in
the area,
while sport
fishing will
only be
permitted
under strict
conditions.
The marine
park is
meant to
protect
biological
diversity,
as fish will
be able to
breed
undisturbed.
“Similar
reserves
worldwide
regularly
see a
five-fold
increase in
fish stocks
compared to
nearby
commercial
fishing
areas,” Onek
said. Click

From
National
Geographic
Magazine
Giant Sea
Scorpion
was Bigger
than a Man.
A fearsome
fossil claw
discovered
in Germany
belonged to
the biggest
bug ever
known,
scientists
announced
Tuesday. The
size of a
large
crocodile,
the
390-million-year-old
sea scorpion
was the top
predator of
its day,
slicing up
fish and
cannibalizing
its own kind
in coastal
swamp
waters,
fossil
experts say.
Jaekelopterus
rhenaniae
measured
some 8.2
feet (2.5
meters)
long,
scientists
estimate,
based on the
length of
its 18-inch
(46-centimeter),
spiked claw.
The find
shows that
arthropods—animals
such as
insects,
spiders, and
crabs, which
have hard
external
skeletons,
jointed
limbs, and
segmented
bodies—once
grew much
larger than
previously
thought,
said
paleobiologist
Simon Braddy
of the
University
of Bristol
in the
United
Kingdom.
"This is an
amazing
discovery,"
Braddy said.
"We have
known for
some time
that the
fossil
record
yields
monster
millipedes,
supersized
scorpions,
colossal
cockroaches,
and jumbo
dragonflies,"
he added.
"But we
never
realized,
until now,
just how big
some of
these
ancient
creepy-crawlies
were." The
newfound
fossil
creature is
estimated to
be at least
one and a
half feet
(46
centimeters)
longer than
any
previously
known
prehistoric
sea
scorpion, a
group called
eurypterids. Click

Mississippi
State
University
Modified
Vaccine
Protects
Catfish from
Bacteria.
Mississippi
State
University
researchers
are working
to develop a
new vaccine
to protect
catfish from
a
devastating
bacterial
disease that
costs the
industry
millions of
dollars each
year.
The U.S.
Department
of
Agriculture
has awarded
more than
$371,400 to
MSU’s
College of
Veterinary
Medicine to
study
enteric
septicemia,
or ESC.
Researchers
believe a
modified
live vaccine
against the
disease
could
dramatically
reduce
economic
losses to
catfish
farmers.
Project
director
Attila Karsi,
an assistant
research
professor,
said enteric
septicemia
is a
bacterial
disease that
costs the
catfish
industry $50
million to
$60 million
each year.
First
identified
in 1976, the
disease has
impacted
Mississippi’s
catfish
production
every year.
The state’s
catfish
industry was
valued at
nearly $273
million in
2006.
“Finding
safe and
effective
vaccines to
protect the
nation’s
most
important
aquaculture
industry is
an urgent
priority,”
Karsi said. Click

At the
University
of
Cincinnati
Zebra
Fish Help
Study of
Human
Diseases.
University of
Cincinnati
researchers
hope their
study of the
tiny
black-and-white
striped
zebrafish,
whose
systems
closely
track those
of humans,
will lead to
enhanced
research on
human
diseases. A
$1.53
million
four-year
grant from
the National
Institutes
of Health is
targeted at
creating a
camera that
will allow
more
detailed
study of
zebrafish
cells. Jay
Hove, an
associate
professor of
molecular
and cellular
physiology,
is working
to develop
the camera
that would
improve the
study of
cell and
fluid
movement in
real time.
He also
hopes to
develop a
course for
fall 2008.
"That's my
mission
here, to
create an
internationally
recognized
research
program,"
said Hove,
43, formerly
of the
California
Institute of
Technology.
"I saw
myself
fitting in
with what
they were
doing here."
The tropical
fish that
belongs to
the minnow
family makes
a good
research
subject
because it
breeds
quickly. "I
can
literally
say, 'I need
10,000
babies next
Wednesday,'"
said Hove,
who was
hired in
2004 to
establish
the program.
Other
scientists
have studied
zebrafish.
Last year,
Dutch
researchers
said they
believe they
have
identified
the gene
that
determines
brain size
in zebrafish,
a finding
that could
eventually
help in
developing
therapies
for humans
suffering
from nervous
system
illnesses
like
Parkinson's
Disease.
While
genetically
distant from
humans, the
zebrafish
has
comparable
organs and
tissues,
such as
heart,
kidney,
pancreas,
bones, and
cartilage.
"The
zebrafish is
therefore a
powerful
model
organism for
understanding
normal
development
and birth
defects, and
providing
clues to
cure human
diseases,"
Dr.
Franziska
Grieder, an
official
with the
National
Center for
Research
Resources, a
component of
the National
Institutes
of Health,
said Monday. Click
